Hard to say:
If the rash is moving from a local to a general distribution it is unlikely a simple contact dermatitis like poison ivy. Generalized rashes can be secondary to an infection (virus or bacteria) a food reaction or bug bites. Without examining the rash it is hard to speculate on a cause or specific treatment. If it itches, Benadryl can be given for comfort.

Such as a lot of irritation and maybe a skin infection at the bite site.

One's dentist can do a twice-a-year dental cleaning. If continued concerns, no more cunnilingus.

However, in general, rashes that itch would respond to an antihistamine (benedryl). A rash that is not changing can be watched to see if it would resolve on its own. And the opposite, rash that is getting worse should be seen within days by the doc.

Sometimes rashes start for no obvious reason, and then continue, especially if scratched.
